NAME

       NetPacket::ICMPv6 - Assemble and disassemble ICMPv6 (Internet Control Message Protocol for IPv6) packets.

VERSION

       version 1.7.2

SYNOPSIS

         use NetPacket::ICMPv6;

         $icmpv6_obj = NetPacket::ICMPv6->decode($raw_pkt);
         $icmpv6_pkt = NetPacket::ICMPv6->encode($ipv6_pkt);
         $icmpv6_data = NetPacket::ICMPv6::strip($raw_pkt);

DESCRIPTION

       "NetPacket::ICMPv6" provides a set of routines for assembling and disassembling packets using ICMPv6
       (Internet Control Message Protocol for IPv6).

   Methods
       "NetPacket::ICMPv6->decode([RAW PACKET])"
           Decode  the  raw  packet  data given and return an object containing instance data.  This method will
           quite happily decode garbage input.  It is the responsibility  of  the  programmer  to  ensure  valid
           packet data is passed to this method.

       "NetPacket::ICMPv6->encode($ipv6_obj)"
           Return  an  ICMPv6  packet  encoded with the instance data specified.  Needs parts of the IPv6 header
           contained in $ipv6_obj in order to calculate the ICMPv6 checksum.

   Functions
       "NetPacket::ICMPv6::strip([RAW PACKET])"
           Return the encapsulated data (or payload) contained in the ICMPv6 packet.

   Instance data
       The instance data for the "NetPacket::ICMPv6" object consists of the following fields.

       type
           The ICMPv6 message type of this packet.

       code
           The ICMPv6 message code of this packet.

       cksum
           The checksum for this packet.

       data
           The encapsulated data (payload) for this packet.

           none

EXAMPLE

       The following example prints the ICMPv6 type, code, and checksum fields.
